I did not see this as a critique of Aldora as much as a "I had great dives, here is what would have made my experience better". I think Dave took this personally, and it wasn't meant that way. It does not alter my perception of Dave, and Aldora is who I dive with when I'm (rarely) in Cozumel. I expect the person at the dive shop who answers emails has explained why s/he didn't respond to the OP, and that will not be an issue in the future.
OTOH, Dave has done this longer than I did. I was tired, cranky, and had had all of the divers I ever wanted to when I had the opportunity to sell. Dave (and indeed Cozumel) has been blasted with bad news in the past week with a State Department warning. I survived the Macondo blowout even though not a drop of oil came ashore in the Florida Keys. So I know where Dave is coming from.
Time to take a deep breath and have a vacation, Dave.
